Hardware Offloads
Posted: Thu Feb 18, 2021 9:23 am
Hello,
our Provider sent us a mail.
Dear IONOS user,
We would like to inform you about upcoming network maintenance in our data centers in Frankfurt and Las Vegas.
To avoid network problems and/or performance issues you must ensure the network settings within the operating system of your VM are adjusted:
• all network interfaces are configured with an MTU size of 1500
• hardware offloads are activated on all network interfaces
the mtu on our tun network for openvpn is correct.
But I connot set hardware offloads to on.
ethtool -K tun0 tx on tso on
Could not change any device features
ethtool -k tun0
Features for tun0:
rx-checksumming: off [fixed]
tx-checksumming: off
tx-checksum-ipv4: off [fixed]
tx-checksum-ip-generic: off [requested on]
tx-checksum-ipv6: off [fixed]
tx-checksum-fcoe-crc: off [fixed]
tx-checksum-sctp: off [fixed]
Is there any possibility to set this option in the openvpn configuration ?
Kind regards
Matthias Kirsch
